Originally designed for use within OpenStack clusters,
Fernet is intended to be fast and light-weight, with
non-persistent tokens. Fernet tokens are signed with a
SHA256 HMAC and their contents encrypted with AES128
in CBC mode.

Fernet Haskell Implementation

Fernet generates and verifies HMAC-based authentication tokens.

Originally designed for use within OpenStack clusters, it was intended
to be fast and light-weight, with non-persistent tokens. Integrity and
confidentiality of the token contents are implemented with HMAC SHA256
and AES128 CBC.
